Feeding device capable of vibrating

Abstract

The invention discloses a feeding device capable of vibrating. The feeding device comprises a bucket body, wherein the bucket body comprises a circular-ring shaped charging section, an inverted cone-shaped material storage section and a circular-ring shaped discharging section which are coaxially arranged; the top end of the material storage section is flexibly connected with the charging section; the bottom end of the material storage section is flexibly connected with the discharging section; a rack is arranged outside the charging section; the rack is connected with the outer side of the charging section; a vibrator is arranged on the side wall of the material storage section; the material storage section is provided with a plurality of screen meshes which are arranged at intervals from top to bottom and are in detachable connection; sieve pores of adjacent two screen meshes are arranged in a staggered manner; shaft through holes are formed at centers of the screen meshes; a cover plate is arranged on the top of the charging section; the cover plate is provided with a charging hole; a drive motor is arranged on the top of the cover plate; the drive motor is connected with a main shaft; the main shaft extends into the bucket body and passes through the shaft through holes to reach the discharging section; a spiral blade is arranged at the tail end of the main shaft; and the spiral blade is arranged in the discharging section. The feeding device capable of vibrating can be used for avoiding material accumulation and is easy for feeding.

Description

technical field [0001] The invention relates to the technical field of extruder equipment, in particular to a vibrating feeding device. Background technique [0002] The host of the plastic extruder is the extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. At present, the automatic metering system is used for feeding the plastic extruder. The plastic and powder are stored in the large feeding hopper, and the stored material is fed to the extrusion equipment through the automatic metering system. In principle, as long as there is material in the feeding hopper, production can be done. Continuous, so keeping the feed hopper filled is critical. The existing feeding hopper has a large volume, and a large amount of materials can be poured in at one time, and enter into the feeding port of the plastic extruder from top to bottom by utilizing the gravity without power. However, due to the accumulation of a large amount of mate...

Problems solved by technology

However, due to the accumulation of a large amount of material in the feeding hopper, this feeding method will easily cause the material at the outlet of the feeding hopper to be blocked, forming a "bridging" phenomenon, which will affect the normal feeding of the feeding hopper, thus causing the plastic extruder to break. The material is idling, and the production cannot continue. At the same time, it has a great impact on the service life of the screw and barrel of the plastic extruder. The manufacturer must equip a special person to stir in the hopper, and the feeding effect fluctuates greatly.

However, the existing forced-feeding adopts the spiral downward pressure type, and the screw downward pressure structure is used in the feeding hopper, which not only often gets stuck due to the uneven size of the material, but also consumes a lot of energy during the long-distance screw pressing process. It is easier to cause the temperature in the feeding hopper to rise and make the material sticky and difficult to feed
